Portfolio overview

Nishikawa Rubber Co., Ltd. has been granted 118 US utility patents between 2015 and 2025, placing Nishikawa Rubber Co., Ltd. at rank #3,181 across all assignees tracked by PlainPatent. This portfolio spans 34 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.7 claims per patent with primary concentration in B60J (WINDOWS, WINDSCREENS, NON-FIXED ROOFS, DOORS, OR SIMILAR DEVICES FOR VEHICLES; REMOVABLE EXTERNAL PROTECTIVE COVERINGS SPECIALLY ADAPTED FOR VEHICLES). As a Foreign Corporation, Nishikawa Rubber Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Nishikawa sits between Holley Performance Products, Inc. (118 patents, rank #3,177) and Samsung LIFE Public Welfare Foundation (118 patents, rank #3,185) - the closest US assignees by grant volume. The composite Innovation Score of 47.9/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 66 grants, compared with 52 in the 2015–2019 window, a +27% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Nishikawa Rubber Co., Ltd.'s 7.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 34 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Nishikawa Rubber Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
